Hello, I am currently working with my lessons instructor in relaxing and breathing better. I am also starting on working on using air to play high, and not pressure, which will be a HUGE thing for me once we can get that through, because then I'll be able to play with much less pressure (still some as there always has to be a little) and have a much, much better endurance and overall sound. But my question is about my current state. I apply quite a bit of pressure to my upper lip which I play higher, and I get a nice single cut line across the inside on my upper lip, which becomes a problem for me. I'm only a sophomore in high school, and want to go into performance as a career, as I have a great passion for performing. I'm very worried about "popping my lip" as I hear. What exactly is it when someone "pops their lip?" I'm scared something will happen to me where I'll have to form a new embouchure and everything (although it's possible I may need to form a new embouchure either way). So what exactly does it mean to "pop your lip" and how serious are these injuries? And, although not easy to say online, does it sound like I might be heading into this danger? Thank you very much.
